An image forming apparatus includes: a driving source configured to generate power; a first rotator configured to be drivingly rotated by the power generated by the driving source; a first power transmission system configured to transmit the power from the driving source to the first rotator; a second rotator configured to be drivingly rotated by the power generated by the driving source; and a second power transmission system configured to transmit the power to the second rotator from the first power transmission system. A damper having a torsion spring constant and a torsion viscous damping constant making a maximum positional change value of the first rotator equal to or smaller than a predetermined positional change value is disposed between the first power transmission system and the second power transmission system.
